, _(*1)

This package is a library for performing a simple to file operations hacklang.
Will provide a lightweight and simple api to the user., _(*2)

Basic usage

Read processing of files can be realized by a simple code as follows., _(*3)

Reading one line at a time.

use HHPack\File\FileLineStream;

$lineStream = FileLineStream::fromString('/path/to/text.log');

foreach ($lineStream as $line) {
    echo $line->length(), "\n"; //output length
    echo $line->value(), "\n"; //output content
};

Read the CSV file

use HHPack\File\FileLineStream;
use HHPack\File\SeparatedRecordStream;
use HHPack\File\ColumnSpecification;

$spec = new ColumnSpecification(',', '"');
$spec->addColumn(0, 'name');
$spec->addColumn(1, 'description');

$lineStream = FileLineStream::fromString(__DIR__ . '/example.csv');
$csvStream = new SeparatedRecordStream($lineStream, $spec);

foreach ($csvStream as $record) {
    echo $record->get('name'), "\n";
    echo $record->get('description'), "\n";
}

Customizing the reading of the record

Will create a parser that implements the ParseSpecification.
Then use the ParsedFileReader, and then apply the parser., _(*4)

use HHPack\File\FileLineStream;
use HHPack\File\ParsedChunkStream;
use HHPack\File\ParseSpecification;

final class CustomRecordSpecification implements ParseSpecification<array<string>>
{
    public function parse(Chunk $line) : array<string>
    {
        return $line->split(',');
    }
}

$spec = new CustomRecordSpecification();
$lineStream = FileLineStream::fromString(__DIR__ . '/example.csv');
$csvStream = new ParsedChunkStream($lineStream, $spec);

foreach ($csvStream as $values) {
    echo $values[0], "\n";
    echo $values[1], "\n";
}
